Specification of Letters Patent.

Application filed October 28, 1915. Serial No. 58,463.

To all whom it may concern:

Be it known that I, JEFFERSON B. HAYDEN, a citizen of the United States,residing at San Angelo, in the county of Tom Green and State of Texas,have invented certain new and useful Improvements in Cotter-Pin Pullers,of which the following is a specification.

This invention relates to tools and more particularly to cross handledtools having two operating or engaging jaws.

The principal object of this invention is to provide a device of thischaracter that will be used principally to pull cotter pins that aresecured in shafts, fly wheels or any other of the numerous devices inwhich they are employed.

It is well known that wire pliers and pincers have been used to pullcotter pins, also claw hammers, and numerous makeshifts such as drivinga nail through the cotter pin head have been employed but all of thesemethods have proved unsatisfactory in that they bend and twist the pin,and in many parts of machines in which cotter pins are used thesemakeshifts can not be employed for lack of space.

Another object of this invention is to provide a device for pullingcotter pins by one operation without bending or twisting or damagingthem, and which will permit of being worked in machinery where the partsare difficult of access or the space restricted or limited.

Other objects such as simplicity, cheapness in manufacture, durabilityand the general improvement of the art will be more fully brought out inthe following specification and illustrated in the accompanyingdrawings, in which:

Figure 1 is a side view of my device open, Fig. 2 is a similar viewclosed, Fig. 3 is a top plan view of Fig. 1, and Fig. 4: is a bottomplan view of Fig. 1.

As shown in the drawings, the device comprises two portions 1 and 2,having operating handles 3 and 4 flattened at 5 and 6, respectively, toform hand grips.

The portion 1 is enlarged at 7 and bent upwardly and forward forming anengaging jaw 8. This jaw 8 is split at 9 forming portions 10 and 11 andhas serrated portions 12. The portion 2 is flattened at 13 and has itsend bent upwardly forming a jaw 1-1 terminating in a point 15. The jaw14: is adapted to be inserted between the portions 10 and 11 of the jawS and pivotally held therebetween by pivot 16 passing through apertures17 and 18.

The operation of the device is as follows: The point 15 of the jaw 14;is passed through the eye of the cotter pin and the serrations 12 of thejaw 8 brought into engagement with the body having the cotter pintherein, and by pressing the hand grips or portions 5 and 6 together thepoint 15 being in the eye of the cotter pin will draw the pin out.

Having thus described my invention what I claim is:

A cotter pin puller consisting of a pair of members, one of said memberscomprising a handle portion and an enlarged jaw extending upwardly andforwardly from said handle portion, said jaw comprising two spacedportions, the forward ends of said spaced portions being bent downwardto form bearing surfaces and said bearing surfaces having serrationsthereon, the other of said members comprising a handle portion ending ina tapered pin engaging portion pivoted between said jaw portions, saidpin engaging portion being curved upwardly and terminating in a point,said tapering pin engaging portion being so curved as to extend betweenand above said spaced portions of said jaw and of such thickness as toleave clearance for a cotterpin head between its sides and the innersides of said spaced jaw portions.

In testimony whereof I hereto affix my signature in the presence of awitness.
